Abstract: Revealing the regulation mechanism of forest on snow and water resources is of great significance. However, the effect of forest on snow hydrological process is poorly understood in the area of northeast China so far. From 2012 to 2013, three forests were selected as the research areas among the experimental wood farms of Harbin. Through regular observation of the snow depth, snow density and snow equivalence of the interior and exterior forests, the influence of different forests on snow water equivalence component was studied. The results showed that the peak snow accumulation period was March 9, 2013. The snow depth of Pinus sylvestris and Larix gmelinii was 20.1% (5.98 cm) and 13.7% (4.08 cm) smaller than that of the clearing respectively. The snow density of different forests’surface and the environmental temperature were significantly and positively correlated. The snow density of Pinus sylvestris and Larix gmelinii was smaller than that of Betula platyphylla and the clearing. The peak snow water equivalence (SWE) of Pinus sylvestris, Larix gmelinii and Betula platyphylla was 32.9%, 14.2% and 7.0% smaller than that of the clearing respectively. During the ablation period, ablation rates of Pinus sylvestris, Larix gmelinii and Betula platyphylla were 39% (1.21 mm/d), 70% (2.18 mm/d) and 93% (2.89 mm/d) as rapid as that of the clearing, respectively. Compared with Larix gmelinii, Betula platyphylla and the clearing, the snow accumulation of Pinus sylvestris surface melt completely 10 days later. The accumulation snow interception of Pinus sylvestris, Larix gmelinii and Betula platyphylla was 18.4 mm, 7.95 mm and 3.89 mm respectively in winter. Above all, the regulation effect of Pinus sylvestris forest on snow redistribution is obvious and the dense canopy structure of Pinus sylvestris forest is an important influencing factor on snow redistribution.
